I'm trying to run my jruby application on trinidad.
Following the readme, I included the trinidad gem in the gemfile and ran
rails server -e production -p 80 -d trinidad
When I access my server with a browser, it gives me an error message about how it can't find the correct class for my database driver, which is in lib/odbc6.jar and works fine if I run the project using WEBrick. The error message looks like this:
org.jruby.rack.RackInitializationException:
load error: /home/bdares/project/config/environment
java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:#(my_jdbc_connection_string)
What am I doing wrong?
Plz try to setup $CLASSPATH global var.

I'm new to podman, and I just trying to run containers on it.
(podman version 3.4.0, installed by brew, intel Core MAC)
However, when I trying to run "podman run {image-name}", below errors were thrown.
$ podman run -ti -d --name web httpd 125
Error: error configuring network namespace for container b0e70d672cb66005833c0a300c8661b88eab49e942c240d69d17587e0b75c47b: error adding pod web_2_web_2 to CNI network "podman": unexpected end of JSON input
$ podman run centos:7
Error: error preparing container a6d0bc1ad217cd8207935561dc8ff7bd33672da3fa513917f9965cb39520c449 for attach: error configuring network namespace for container a6d0bc1ad217cd8207935561dc8ff7bd33672da3fa513917f9965cb39520c449: error adding pod quirky_snyder_quirky_snyder to CNI network "podman": unexpected end of JSON input
By reading https://issueexplorer.com/issue/containers/podman/11452, I removed ~/.docker/, but the solution doesn't work in my case.
Of course, the error message says there was "unexpected end of JSON input", but I don't know how to fix it. Could anyone guess why podman didn't work even running these base images, or how to debug it?
Thanks in advance.
on macos, current machine version 3.3.1 has this problem. I had this problem on server version 3.3.1 and I do not encounter it on server version 3.4.0. You can check server version with podman version.
Try removing current machine and installing a newer one
podman machine stop
podman machine rm
podman machine init --image-path next
podman machine start
Check server version again with podman version.
Try running your image again.
Does the MySQL-server and PHP5-MySQLi version have to match in order for a connection to be possible? I'm currently receiving the error below: I am running BSD.
"Fatal error: Uncaught exception 'PDOException' with message 'could not find driver'..."
Here is the the connection info:
$info = "mysql:dbname=myDB;host=localhost";
$user = "dbUser";
$pw = "somePW";
return(new PDO($info, $user, $pw));
Here is my MySQL information:
mysql-server-5.5.24
php5-mysqli-5.4.3
I had this same issue on my CentOS install. I had tried to install imagick and hosed my install. When I removed all of my php files and reinstalled something wasn't working right.
I ran:
yum install php-pdo
yum install php-pdo_mysql
After doing those two lines I ran
service httpd restart
and everything came back up and running.
PDO uses database specific drivers to connect to database systems. It looks like you are missing the pdo_mysql driver that is required to connect to a MySQL database. There is some details on installing the driver on the pdo_mysql manual page, or there may be a BSD package that you can use (I am afraid I'm not familiar enough with BSD to offer specific advice).
Thanks to zerkms and John C for pointing me in the right direction. Below are the commands I used to install the driver:
#cd /usr/ports/databases/php5-pdo_mysql
#make install clean
#apachectl restart
I know this is a duplicate question however whatever I tried, unfortunately no luck. (To add, I am using MAMP)
I believe I successfully setup the database connection because, using the registration form (Auth/register), after submitting the form, I was getting the error PDO Exception: Driver not found before, but after changing to my MAMP to PHP 5.5.17 from the default(PHP 5.6.1), I started getting error: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'laravel.users' doesn't exist, which I believe shows that the database connection is working and it's just the 'users table' is not created.
Here starts my problem. When I try to use php artisan migrate or migrate:{anything} in the terminal, it's throwing the error:
[PDOException]
could not find driver
But what I want to do is to use php artisan migrate to be able to create tables and migrate them.
Things I have tried:
I added <?php echo phpinfo(); ?> to if pdo files are successfully installed.
I get the result:
so I think it seems okay.
People were talking about opening /MAMP/bin/php/php5.6.1/conf/php.ini and adding extension=pdo_mysql.so in the code, but I have mine already placed there.
When I try php -i | grep PDO in the project root (/MAMP/htdocs/proj), I got:
PDO
PDO support => enabled
PDO drivers => sqlite
PDO Driver for SQLite 3.x => enabled
php -i | grep Conf and `php --ini also outputs:
Configuration File (php.ini) Path: /Applications/MAMP/bin/php/php5.6.1/conf
Loaded Configuration File: /Applications/MAMP/bin/php/php5.6.1/conf/php.ini but php artisan migrate still throwing the same error
SOLUTION:
I chose MAMP to use version 5.5.17 instead of 5.6.1 in the browser (from MAMP Preferences), however this time terminal was running the 5.6.1. What I did was first checking which PHP command and then, running the nano ~/.bash_profile command; and editing the version document. Now everything is up and running :)
What you see in the browser is that you have PDO enabled for PHP running through apache. But this does not mean you have it enabled for PHP running through CLI (in fact they are using two separate ini files). To confirm that you can try:
php -i | grep PDO
And you will see it is missing or not enabled. So what you need to do is to find which php.ini is using the PHP running through CLI and add the PDO module there:
php -i | grep Conf
It will output something like:
Configuration File (php.ini) Path => /etc/php5/cli
Loaded Configuration File => /etc/php5/cli/php.ini
cPanel is throwing up an error everytime I try to add or edit an existing subdomain. The same error is showing up when I try to add a new database.
Cpanel::AdminBin::_get_cpwrapd_connection could not connect to /usr/local/cpanel/var/cpwrapd.sock
PHPMyAdmin, FTP and SSH are all working perfectly, so the problem is something to do with cPanel. The server is a VPS with GoDaddy. I was installing a program running on Ruby 1.8.7, and this error started showing up after I installed the program. I have tried /scripts/installruby but that's giving me this error:
The internal error was:

I solved the problem by rebooting cPanel, using /etc/init.d/cpanel restart
I'm using JRuby 1.7.2, along with DataMapper, and I'm getting an error I can't find an answer to.
I'm just testing out DataMapper along with MySQL 5.5 to see if it will run fine when I build around it. Here's the file I'm testing:
require "data_mapper"
require "keys"
DataMapper.setup(:default, "mysql://#{$user}:#{$pass}#localhost/test_db")
And when I run this, I get the error:
NameError: cannot load Java class com.mysql.jdbc.Driver
And it points to the DataMapper.setup line.
My Gemfile should be alright:
source :rubygems
gem "sinatra"
gem "trinidad"
gem "data_mapper"
# do a `sudo apt-get install libmysqlclient-dev` first
gem "dm-mysql-adapter"
gem "jdbc-mysql"
Is there anything I'm missing? I have MySQL set up with a user/pass locally already.
This is a common error when running JDBC clients for MySQL. You need to make sure you have mysql-connector-java-bin.jar on the classpath. You can download it from here.
I'm using Rails 3.2.9 and to solve the problem I added this to my application.rb
if defined? JRUBY_VERSION
require 'jdbc/mysql'
Jdbc::MySQL.load_driver
end
actually, the correct answer is to work-around an incompatibility between 5.1.13 and 5.1.22 !
jdbc-mysql gem already contains the mysql-connector.jar it just ain't auto-loading anymore :
https://github.com/jruby/activerecord-jdbc-adapter/tree/master/jdbc-mysql (read the README)
you can also force the driver to auto-load using a Java system property e.g. from a cmd line :
jruby -J-Darjdbc.mysql.autoload=true -S rake ...
I had the same error when trying to use a mysql database from jruby/rails4. In my case this line was missing from ./Gemfile:
gem 'jdbc-mysql'
